PATENT BENNY BERNSTEIN, OF NEW YORK, N. Y.

LOCK.

SPECIFICATION forming part of Letters Patent No. 663,413, dated December 11, 1900.

Application filed July 1, 1899. Serial No. 722,540. (No model.)

To all whom, it may concern.-

Be it known that I, BENNY BERNSTEIN, a citizen of the United States, and a resident of the borough of Manhattan, in the city and State of New York, have invented a new and useful Improvement in Locks or Fasteners for Dress-Suit Cases, Boxes, Straps, and Like Articles, of which the following is a specification.

In my Patent No. 629,763, granted August 1, 1899, I have shown and described a hasplock having a rotary T-bolt carried by the hasp and engaging automatically with an annular rotating keeper mounted on the body of the trunk or other article, the said annular keeper having inwardly-projecting beveled lips, so that the pressure in closing the hasp rotates the keeper backward against the resistance of a spring which restores it to normal position and causes it to engage with the T-bolt. To unlock,the keeper is turned backward by hand, or if the keeper has been locked by a suitable provision for the purpose unlocking can be effected only by means of a key applied to the T-bolt to turn it.

In my present improvement I employ a fixed annular keeper, with inwardly-projecting bevel-faced lips to be applied to the body of the box or other article, and a T-bolt to engage therewith mounted in the hasp through the medium of a rotatable lock-plate which is turned forward by a spring to cause the automatic engagement of the lock with the fixed keeper in closing the hasp and may be turned backward by hand to release the T-bolt from the keeper. The automatic engagement of theT-bolt with the keeper when the hasp is snapped shut is thus effected by the rotation within the hasp of the springpressed lock-plate in which the T-bolt is mounted. The rotatable lock-plate is f urthermore capable of being turned forward by hand beyond the point to which it is turned forward by its spring. When thus turned forward by hand beyond the normal position to which it is turned by its spring, the said rotatable lock-plate is caught by a spring-pin, which prevents its being turned back While the hasp remains closed. In this condition the hasp can only be released by turning the T-bolt in the rotatable plate, and as the turning of the T-bolt in the rotatable lock-plate is controlled by a tumbler-lock mechanism such independent turning of the T-bolt can only be effected by means of a suitable key.

In the accompanying drawings, Figure 1 is a front view of a hasp-lock illustrating my invention, showing the hasp closed. Fig. 2 is a front view of the two members of the same, showing the hasp open. tail section of a portion of the fixed keeperplate in the plane indicated by the dotted line in Fig. 2. Fig. 4 is a view, on a larger scale, of' the inner face of the lock with the outer plate removed. Fig. 6 is a detached view of ing keeper-ring, illustrating a modification.

The annular keeper-plate 2, Figs. 2 and 3, formed with inwardly-projecting bevel-faced lips 3, is secured in fixed position in the body of the dress-suit case, box, or the like, the

T-bolt t, formed with bevel-faced radial lugs ehto engage with the keeper-plate 2, is mounted in a lock-plate L, which is rotatable within a housing on the hasp H. The rotatable lockplate L is turned forward and held normally in engaging position by a spring 5, connected by one end to the hasp and by the other end to the lock-plate L to enable the said lockplate to turn backward as the T-bolt is pressed into engagement with the keeper and cause the bolt to snap automatically into engage- 9o ment with the keeper when the hasp is close In order to provide for locking the hasp,'sjo that it cannot be opened without the use of a key, the rotary lock-plate L is connectechto its spring 5 by a slot 5, permitting lost rno- 5 tion and enabling the plate to be turned forward by hand beyond the position at which it is normally held by its spring by means of an arm or handle Z, projecting rigidly'from the rotary plate L. the lock-plate L is caught and,held by a springpressed stud 12 in the fixed keeper-plate 2 engaging in a hole 13 in the rotary lock-plate L. The hasp is thus efiectually locked, and

Fig. 3 is a de- 60 Fig. Sis a view of the same, showing 70 In this advanced/position 10o in order to unlock it the T-bolt tmust be rotated in the rotatable lock-plate L to disengage said T-bolt from the keeper 2. This rotation of the T-bolttwithin the rotatable lockplate L is efiected by means of a suitable key, which operates in customary manner to force back the spring-pressed tumblers T, by which the T-bolt t is normally held against relative rotation in the rotatable lock-plate L and which compel the backward rotation of the lock-plate against the pressure of its spring when the hasp is snapped shut.

The hasp-lock above described is so construeted that the key cannot be withdrawn therefrom while the bolt 25 is in the retracted position within the lock-plate to which it is turned in unlocking. In order to withdraw the key, it must be so turned as to restore the rotary T-boltt to its normal engaging position. This can be done either with the h asp open or closed. If the bolt is so turned and the key withdrawn while the hasp is closed, the hasp will be left in locked position, so that it cannot be opened without the use of the key, as before. If the bolt is turned into normal position and the key withdrawn while the hasp is open, it leaves the T-bolt in position to snap into engagement with the keeper by the closing of the hasp, and the backward rotation thus imparted to the bolt in closing the hasp turns the lock-plate backward to normal position before the aperture 13 therein can engage with the stud 12, so that when the hasp is snapped shut the parts are in position to permit turning back the lock-plate L by hand to release the hasp or until it is again moved forward, so as to be caught by the spring-pressed locking-stud 12.

When the lock-plate L has not been locked against rotation by turning it forward beyond normal position, as above described, the hasp can be released by simply turning the lockplate backward by means of the arm Z; but for this purpose I prefer to employ a more prominent arm or handle l, projecting from a concentric ring Z having a notch Z working on a pin formed of the upturned end 5 of the spring 5, which pin projects through the said notch Z in the ring Z and into a hole in the rotary lock-plate. The handle Z is limited in its forward movement by a notch in the fixed housing of the hasp in which said handle works, so that in rotating the lockplate L forward beyond normal and into locked position by means of the arm Z the connecting-pin 5 moves in the notch Z in the ring Z but when the rotatable lock-plate L has not been so turned forward beyond normal position the engagement of the forward end of the notch Z with the pin 5 enables the lock-plate to be turned backward by means of the handle Z and ring Z for the purpose of releasing the hasp when simply caught and not locked. It is a matter of convcnience to prevent the locking of the hasp by manipulation of the more prominent handle Z, so that it may not be locked uninten tionally.

In applying the invention to fasteners for belts, dog-collars, and other straps the parts are preferably transposed, as illustrated in Figs. 7, 8, 9, 10, and 11, the T-bolt taking the form of a post i, projecting rigidly from a plate a, riveted to one end of the strap S and formed at its base with a cylindrical boss at to be inserted in anyone of a number of holess at different distances from the other end of the strap, so as to regulate the length of the belt or collar in customary manner. The head of the post 23 is formed with bevel-faced lugs 4: 4:, as before described, to engage with corresponding inwardly-projecting lips 33 on the annular keeper-plate 2, which is mounted in the inner face of a hasp H, hinged at one side of the plate Ct. The annular keeper-plate 2 is capable of limited rotary motion within the hasp and is held in one direction by a spring 5, which yields to the angular or tangential pressure applied to the keeper-plate 2 by the beveled lips 4 of the post t in closing the hasp and causes the hasp to be caught automatically when snapped shut.

The locking and unlocking devices in all their details, as already described, may be used with this form of the invention; but for greater simplicity in hasp-locks of comparatively small size for belts, dog-collars, and other straps 1 may dispense with the special locking-pin and the radial handle 1 for turning the annular keeper-plate, so that the hasp will be locked in closing and can only be opened by means of a suitable key inserted in a keyhole 0c in the outer face of the hasp, or I may dispense with a key and use the handle for unlocking, as illustrated in Fig. 11.

The hinging of the hasp, as shown in Figs. 7, 8, 9, and 10, may be dispensed with and said hasp connected permanently to one end of the strap, to the other end of which the fixed stud t is secured.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent:
